linting: Enable all Ruff rulesets by default

The goal here is to have ruff enable new rulesets when new releases are
made without us having to o anything: we can then decide if we disable
or not.

* Enable a couple more rulesets (ERA, INP, T )
* Add a few individual ignores to tests and examples
* Default to enable all, disable the rulesets we don't want
